Abstract

L'invention concerne un appareil de micro-onduleur amélioré permettant de commander de façon intelligente la récupération d'énergie à partir des panneaux solaires photovoltaïques sur la base d'une ou plusieurs variables réglables définies par un utilisateur. L'appareil de micro-onduleur amélioré peut comprendre un microcontrôleur conçu pour surveiller la température de fonctionnement de son micro-onduleur et pour commander l'énergie récupérée à partir de panneaux solaires associés afin de garantir que la température de fonctionnement du micro-onduleur n'approche pas un niveau qui serait susceptible d'endommager l'ensemble de circuits du micro-onduleur ou d'autres composants. De même, le microcontrôleur de l'appareil de micro-onduleur peut être conçu pour surveiller la distorsion harmonique totale de la puissance de sortie en courant alternatif du micro-onduleur et pour commander l'énergie récupérée à partir de panneaux solaires associés afin de garantir que la distorsion harmonique totale de la puissance de sortie en courant alternatif ne dépasse pas un niveau seuil.
